Mobile Terminal, Television Receiver, and Communication System Including the Mobile Terminal and the Television Receiver

1. A communication system in which a mobile terminal and a television receiver are configured to be interactively communicable with each other, comprising: a transmitter configured to transmit a first Uniform Resource Locator (URL) to the television receiver, wherein the first URL being a mobile URL and being adapted for conversion to a second URL, where the first URL or the second URL operate as a command to power-on the television receiver, and the television receiver is configured to use the second URL to start an application for displaying contents obtained from a server; and a processor configured to (i) automatically switch, after transmission of the first URL, a display of the mobile terminal to a replay operation display or a pointer operation display for operating the television receiver, wherein the replay operation display is displayed if the first URL is addressed to a moving picture site, the pointer operation display is displayed if the first URL is addressed to a website, and (ii) transmit a communication to the television receiver including the first URL and a packet for instructing the television receiver to power-on when the processor receives no acknowledgment within a preset period of time after transmitting the first URL.

2. The communication system according to claim 1 , wherein if an acknowledgment from the television receiver is received after the first URL is transmitted to the television receiver, the processor switches the display thereof to the replay operation display or the pointer operation display.

3. The communication system according to claim 1 , wherein if the television receiver shifts from a power-on state to a standby state or a power-off state, the mobile terminal returns the display to a display thereof assumed before the replay operation display or the pointer operation display.

4. The communication system according to claim 1 , wherein after the first URL is transmitted, the mobile terminal switches the display thereof from an operation display for address transmission to the replay operation display or the pointer operation display.

5. A mobile terminal configured to be interactively communicable with a television receiver and a server on a network, comprising: a transmitter configured to transmit a first Uniform Resource Locator (URL) to the television receiver, wherein the first URL being a mobile URL and being adapted for conversion to a second URL, where the first URL or the second URL operate as a command to power-on the television receiver, and the television receiver is configured to use the second URL to start an application for displaying contents obtained from a server; and a processor configured to (i) automatically switch, after transmission of the first URL, a display of the mobile terminal to a replay operation display or a pointer operation display for operating the television receiver, wherein the replay operation display is displayed if the first URL is addressed to a moving picture site, the pointer operation display is displayed if the first URL is addressed to a website, and (ii) transmit a communication to the television receiver including the first URL and a packet for instructing the television receiver to power-on when the processor receives no acknowledgment within a preset period of time after transmitting the first URL.

6. The mobile terminal according to claim 5 , wherein if an acknowledgment from the television receiver is received after the first URL is transmitted to the television receiver, the processor switches the display thereof to the replay operation display or the pointer operation display.

7. The mobile terminal according to claim 5 , wherein if the television receiver shifts from a power-on state to a standby state or a power-off state, the mobile terminal returns the operation display to a display thereof assumed before the operation display.

8. The mobile terminal according to claim 5 , wherein after the first URL is transmitted, the processor switches the display thereof from an operation display for address transmission to the replay operation display or the pointer operation display.

9. A communication method of a mobile terminal which is configured to be interactively communicable with a television receiver and a server on a network, comprising: transmitting a first Uniform Resource Locator (URL) to the television receiver, wherein the first URL being a mobile URL and being adapted for conversion to a second URL, where the first URL or the second URL operate as a command to power-on the television receiver, and the television receiver is configured to use the second URL to start an application for displaying contents obtained from a server; and automatically switch, after transmission of the first URL, a display of the mobile terminal to a replay operation display or a pointer operation display for operating the television receiver, wherein the replay operation display is displayed if the first URL is addressed to a moving picture site, the pointer operation display is displayed if the first URL is addressed to a website; and transmitting a communication to the television receiver including the first URL and a packet for instructing the television receiver to power-on when the processor receives no acknowledgment within a preset period of time after transmitting the first URL.

10. The communication method of the mobile terminal of claim 9 , wherein an acknowledgment from the television receiver is received after the first URL is transmitted to the television receiver, the processor switches the display thereof to the replay operation display or the pointer operation display is executed.

11. The communication method of the mobile terminal of claim 9 , wherein if the television receiver shifts from a power-on state to a standby state or a power-off state, the mobile terminal returns the display to a display thereof assumed before the replay operation display or the pointer operation display.

12. A communication system in which a mobile terminal and a television receiver are configured to be interactively communicable with each other, comprising: a transmitter configured to transmit a first Uniform Resource Locator (URL) to the television receiver, the first URL being a mobile URL to operate as a command to power-on the television receiver; and a processor configured to (i) determine whether an acknowledgement has been received from the television receiver within a preset period of time and (ii) transmit a communication including the first URL and a packet for instructing the television receiver to power-on when no acknowledgment has been received.

13. The communication system of claim 12 , wherein the processor is further configured to automatically switch, after transmission of the first URL, a display of the mobile terminal to a replay operation display or a pointer operation display for operating the television receiver, wherein the replay operation display is displayed when the first URL is addressed to a website of a moving picture, the pointer operation display is displayed when the first URL is addressed to a website not of a moving picture.

14. The communication system of claim 12 , wherein the second first URL is converted to a second URL, the second URL (i) being a non-mobile URL, (ii) adapted to act as a command to power-on the television receiver, and (iii) adapted to start an application for displaying contents obtained from a server.
